1.Structure of Gate Valve Description

A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

5.FAQ

1. What's are the characteristics of gate valve?

The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. 

2. What is the work principle of gate valve

 The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:Does the relief valve have a gate valve?
With the ball valve, needle valve, with the valve did not see, but there should be some.
Q:The difference and use of gate valve and stop valve
Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.
Q:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:Acid resistant alkali valve gate valve
Fluorine gate valve; material: carbon steel, cast iron; design standards: JB, GB, ANSI, BS, API, ISO, DIN, NFZ, lining valve;
Q:What gate valve is the J41H-150LBDN100 gate valve?
This is a stop valve, not a gate valve.Gate valve means Z41H-150LB-DN100Wenzhou shintex Valve Manufacturing Co. Ltd.0577Eight thousand six hundred and ninety-oneSeven thousand five hundred and sixteenCall
Q:Does the tap belong to a stop valve or a gate valve?
If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve
Q:What is a protective gate valve? What is gate valve knowledge?
Door gate, refers to the design of anti blocking nuclear explosion shock wave from the pipe into the project inside the valve, composed of a valve body, valve seat, valve plate and wave absorbing device, wave absorbing device leakage hole in the valve body, valve leakage hole is a cylindrical hole, wave valve has two door sealing groove between the cylindrical hole and wave valve double seal ring seal, between the valve body and the flange is double sealing ring seal.
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
Q:What is gate well?
Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.
